Descriptions of New Species of Freshwater Shells Collected by Mr. F.g. Waterhouse, During J. McDOUALL Stuart’s
Overland Journey from Adelaide to the North-West Coast of Australia. By Arthur Adams, F.l.s., and G. French Angas,
Corresponding Member of the Zoological Society.

This fine species most nearly resembles Vivipara ussuriensis, Gerst.; but the last whorl is more inflated, and the
surface of the shell is not malleated or lirate. It is the largest species yet discovered on the Australian continent.
We have great pleasure in dedicating it to F.G. Waterhouse, Esquire, who, under great difficulties during the
expedition, succeeded in making many valuable additions to science.

This is a neat, finely-decussated, concolorous species, with the upper whorls nodulous from erosion, as in Vivipara
praerosa, Gerst. It is named after Mr. Stephen King, one of the gentlemen who accompanied the expedition.

A species remarkable both for the elegance of its form and the beauty of its painting. The whorls are plicate, with
a necklace-like series of nodules at the sutures; and the shell is covered with dark red-brown spots, suggestive of its
specific name.

This species may readily be distinguished on account of its peculiar vinous colour. The whorls are posteriorly
gibbose or tumid at the sutures, and the callus is less spreading than in others of the genus.

We have much pleasure in naming this noble Physa after Dr. Newcomb, the distinguished American conchologist, who has
contributed so much, by his researches in the Sandwich Islands, to our knowledge of the genus Helicter or Achatinella.
The species is widely umbilicated, and the peristome is usually dark-coloured.

We have much pleasure in dedicating this singular species to Mr. Lovell Reeve, who has evinced much interest in the
shells of this group. The last whorl is acutely angulate posteriorly, and the spire is tabulated, giving to the shell a
peculiar truncate appearance.

This species, which we have named after Mr. J. McD. Stuart, the leader of the expedition, is the only Naiad, besides
Alasmodon angasana of Lea, yet discovered in the regions traversed by the explorers.

Description of a new Helix from the interior of Australia, by Dr. L. Pfeiffer.

Dodonaea microzyga, F.M. Somewhat viscid, almost glabrous; leaves with 1 to 2 pairs of small obovate-cuneate
leaflets; in front rounded, or truncate, or retuse, or sometimes 3-toothed, flat at the margin; rachis dilated;
fruit-bearing pedicels solitary; capsules 3 to 4-celled; valves cymbeo-semiorbicular, all around broadly winged; the
wing rounded-blunt on both extremities; dissepiments persistent with the columella. On the River Neale. J.M.
Stuart.

A shrub with spreading and rigid branches. Most leaves about 1/2 an inch long; leaflets 1 to 2 inches long; flowers
unknown; capsule with the wings added about 1/2 an inch long, shining, reddish; valves ceding from the septa; ripe
seeds unknown.

Didiscus glaucifolius, F.M. in Linnaea, 1852, page 395. Var. cyanopetalus. Finke River. J.M. Stuart. The colour of
the petals varies likewise blue and white in Didiscus coeruleus and in one species of Dimetopia.

Helichrysum Cassianum, Gaudichaud Voyage Freycenet. page 466, t. 87. (Sect. Pteropogon.) River Finke. J.M. Stuart.
The capitula are rather smaller than those figured by Gaudichaud; but in Mr. Oldfield’s collection from the Murchison
River we observe analogous specimens, with intermediate gradations. The involucre-scales are sometimes delicately
rose-coloured.

Jasminum calcarium, F.M. Fragm. i. 212. Common to most creeks of the interior. Stuart. The lobes of the calyx are
narrower than in the specimens from the Murchison River; the lobes of the corolla likewise narrower, and occasionally
augmented to nine. The leaflets sometimes ovate. Transient forms are sent from Champion Bay by Mr. Walcott.

Gomphrena humilis, R. Br. Prodr. 416. Attack Creek. The upper pair of leaves stand either next to the flower-heads
or remote from them. The same species has been found by Dr. Muller on the Dawson River, and by Mr. Fitzalan at Port
Denison.

Ficus Stuartii, F.M. McDonnell Range; Brinkley Bluff. Several other undescribed species of fig-trees occur in the
collection, but cannot be satisfactorily characterised from the material extant.

Cycadeae.

A cycadeous plant, seemingly distinct from the seven Australian species, occurs on McDonnell Range, and is mentioned
as a palm in the Journal of the explorers. Only leaves being now submitted for examination, it remains for future
researches to throw light on this plant.

Amaryllideae.

Calostemma luteum, Sims, in Botanical Magazine 2101. Mount Margaret. Stuart. The edge of the corona is sometimes
rather undulated than toothed.
